MVT Interactive Diagnostic
MVT Interactive Diagnostic is a free, interactive learning demo from the AP Calculus AB course on Lykke. It helps you build intuition for Mean Value Theorem (MVT), Extreme Value Theorem (EVT), First Derivative Test (Increasing/Decreasing), Second Derivative Test (Concavity). Play with it directly in your browser — it features direct drag interaction and a live visual canvas. This demo lives in the “Unit 5: Analytical Applications of Differentiation” section of the course.

How to use this demo
- Click and drag directly on the canvas to manipulate the scene.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Mean Value Theorem (MVT)
- Extreme Value Theorem (EVT)
- First Derivative Test (Increasing/Decreasing)
- Second Derivative Test (Concavity)
- Points of Inflection
- Optimization Problems
- Candidates Test for Global Extrema
Frequently asked questions
What does the MVT Interactive Diagnostic demo do?
Students use derivatives to analyze the behavior of functions, including finding extrema, determining concavity, and sketching accurate graphs. This unit also covers optimization problems. MVT Interactive Diagnostic turns that idea into something you can manipulate directly and watch respond.
What AP Calculus AB concept does MVT Interactive Diagnostic teach?
Students use derivatives to analyze the behavior of functions, including finding extrema, determining concavity, and sketching accurate graphs. This unit also covers optimization problems. It focuses on Mean Value Theorem (MVT), Extreme Value Theorem (EVT), First Derivative Test (Increasing/Decreasing), Second Derivative Test (Concavity), Points of Inflection, Optimization Problems from the “Unit 5: Analytical Applications of Differentiation” section.
What can I control in MVT Interactive Diagnostic?
You can drag elements directly on the canvas. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does MVT Interactive Diagnostic fit into the AP Calculus AB course?
AP Calculus AB is a college-level course that explores the concepts of limits, derivatives, and integrals. Students learn to approach mathematical problems through multiple representations—graphical, numerical, analytic… This demo is the interactive piece for the “Unit 5: Analytical Applications of Differentiation” section.

What will I understand better after using MVT Interactive Diagnostic?
You'll build intuition for Mean Value Theorem (MVT), Extreme Value Theorem (EVT), First Derivative Test (Increasing/Decreasing), Second Derivative Test (Concavity), Points of Inflection, Optimization Problems — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on AP Calculus AB alone.
